Pressure Indicator for Automotive Radiator, senses a predefined pressure and flags off a permanent trigger.

ABSTRACT

The invention, the pressure indicator is thread fitted onto the Radiator; the pressure indicator is designed to conduct 2 unique functions of sensing the pre decided max sustainable pressure and communicating the same. Once the pre-decided maximum sustainable pressure of the Radiator is reached, the spring gets actuated and allows air to flow inside the pressure indicator assembly. The air flow pushes the arrow head component; the top portion of the component penetrates through the rubber retainer center hole into the visible transparent zone of the assembly. The retainer rubber and the transparent tube only allow the partial passage of the arrow head component and entrap its base stem portion permanently, hence permanently flagging off the indicator. The flagged component is visible through the transparent tube, indicating that the pressure has been breached.

BACKGROUND OF THE INVENTION

Automotive Radiators Manufacturers are thrust with claims of Radiator non performance. Whereas in some cases the pressure generated by the engine is far more than the defined sustainable pressure of the Radiator. Under such cases the Radiator bursts, but yet the claim has to be given as there is no evidence of surplus pressure.

BRIEF SUMMARY OF THE INVENTION

As stated above, in some cases the pressure generated by the engine is far more than the defined sustainable pressure of the Radiator. Under such cases the Radiator burst, but yet the claim has to be given as there is no evidence of surplus pressure. The invention claimed here solves this problem.

The Pressure Indicator sense that the pre-decided maximum sustainable pressure of the Radiator has been reached and communicates the same with flagging off an arrow head component, which stays flagged permanently.

The objective of this invention is that any damage or malfunctioning to the Radiator after the indicator flags off would not be a responsibility of the manufacturer, as the pre-defined sustainable level of the Radiator has been crossed.

Relationship Between the Components:

The Pressure Indicator comprises of 11 baby components, can be divided into 2 distinct functions; the actuating function and the indicating function. The actuating function sense the breach of pre-decided pressure and the indicating function communicates by triggering off the flag.

The following is the description of the baby components, their fitment in the entire system along with their respective functions.

The Product Pressure Indicator comprises of

-   -   1. Threaded Base—this component is thread fitted onto the         Radiator threaded insert at the bottom end and snap fits the         main body at the top end. It also acts as a casing to the         various internal components, which participate in the actuation         function.     -   2. Main Body—this component is snap fitted to the threaded base         at the bottom end. Back bone to the Indicative function of the         Pressure Indicator. It encompasses indicator and the retainer on         the inside, allowing the indicator a passage to shot off in the         pressurized position and get griped or entrapped onto the         retainer.     -   3. Top Lid—Is Joint at the bottom end with the main body, the         component enables the placement of the transparent case         component.     -   4. Transparent Tube—Ensures display of the indicator in the         pressurized position and ensuring non-tampering of the assembly.         It also keeps the retainer compressed at the base end, to ensure         a leak proof joint. The transparent tube may have small holes         for the coolant to discharge off.     -   5. Spring Guide—As the name suggests, it guides and locates the         spring. Placed inside the cavity of the thread base has         systematic gaps on the outer ring area to allow air to flow         through.     -   6. Lower Rubber Seal—Part of the actuating function is placed         between the spring guide and the internal base area of the         threaded base. To ensure a leak proof joint.     -   7. Compression Spring—Designed to ensure actuation at the         pre-desired pressure is the heart of the actuating function. The         spring compresses at reaching the Radiator's maximum sustaining         pressure, allowing air to flow through.     -   8. Main Rubber Washer—Placed at the undercut of the threaded         base, helps seal the joint between the Pressure Indicator and         the threaded insert of the Radiator.     -   9. Sealing Ring—Placed between the threaded base and the main         body ensuring a seal proof joint.     -   10. Arrow Head Component—The Flag which gets activated at         reaching the pre-desired pressure. Placed in the cylindrical         inside channel of the Main body shoots off by pressurized air         and gets entraps in the retainer.     -   11. Retainer—Is a Rubber Component with a hole in the center,         Placed inside the main body top groove does a dual function of         sealing the joint with help of the transparent case. More         importantly and as the name suggests, it ensures entrapment of         the indicator once it is actuated so that it does not retract         back on gravity and stays flagged.

How the Invention Works:

The Pressure Indicator is thread fitted onto the Radiator. The Radiator is kept pressurized and is designed to sustain certain pressure. Crossing the maximum sustainable pressure, the Radiator would burst, get damaged. The pressure indicator helps communicate when the maximum sustainable pressure of the Radiator has been reached.

The Pressure Indicator is an assembly of 11 components conducting 2 unique functions of actuation and indication. The objective being to sense when the pre-defined pressure has reached by a predesigned compression spring and communicate the same with a flagging off the arrow head component, which stays flagged permanently.

The Pressure Indicator in the original position as shown in FIG. 1 stays as is, an assembly of 11 components fitted as mentioned above. There is continuous pressure 12 being generated from inside the Radiator. The Main Rubber Washer 8 ensures sealing of the joint between the Pressure Indicator and the threaded Insert of the Radiator.

On reaching the pre-defined pressure, the actuation process starts. The compression spring 7 compresses and gets actuated along with the spring guide 14 and the lower rubber seal 15; the actuation function of the pressure indicator is now complete.

The actuation of the spring give the air flow a passage described by 13 and initiates the indicative stage. The Pressurized air flow pushes the arrow head component 19. The arrow head component 19 gets pushed upwards until it meets the rubber retainer 20. The Rubber Retainer is a rubber component with a hole in the centre. The hole is big enough to allow the initial penetration of the arrow head component, but not big enough for it to completely get through. The Retainer being a rubber component, on additional pressure allows the arrow head component to push itself forward, thus the top part (the arrow head) passes through the rubber retainers centre hole. The base end of the Transparent Tube does not allow the arrow head component to rocket up and restricts it. The Rubber Retainer on allowing the top portion of the arrow head to pass retains its position and grips onto the stem portion entrapping the arrow head component. Thus not allowing the arrow head component to drop back even on gravity.

Thus the pressure breach inside the radiator is communicated by flagging of the arrow head component and the same retains its flagged off position permanently. The Transparent tube enables the visual display of the arrow head component suggesting and communicating that the pressure has been breached. Also the transparent tube enables that the flagged component is not manually tampered with.

How to Make the Invention:

The baby components of the Pressure Indicator are assembled in the described form. Then the entire assembly is thread fitted onto a Threaded insert situated at the top of the tank.

All baby component of a Pressure Indicator are necessary.

How to Use the Invention:

To use this invention, one needs to thread fit the pressure indicator onto the radiator tank insert and let the indicator conduct its function. 

What it claims:
 1. The Pressure indicator sense that the pre-decided maximum sustainable pressure of the Radiator has been reached and communicates the same with flagging off the arrow head component, the component on its return gets trapped by a rubber retainer hence it stays flagged permanently.
